What are the pros and cons of population growth?
I have to do a project on Australia (where I live), so it would be helpful if you know anything specifically about Australia as well.

Pro: keeps a viable population of a given species and in humans at least can produce a great deal of wealth.
Cons: over population can lead to overuse of resources, and eventual collapse of a population by starvation.
Explanation:
A strong population growth means that a species is being successful in reproduction and is well adapted to a particular ecological niche.
In humans, a larger population allows for more economic activity and more wealth for most - though large parts of the human population does not share all of this wealth creation. Some economists worry that too low of a human population growth could lead to stagnation in countries economies.
Over population means that a species is using up all the food and other resources in a region and perhaps is avoiding predation. This usually leads to population crashes through eventual starvation. This is happening in many countries around the world today. Too many people also lead to greater demand for resources, which results in more air, water and land pollution.
